Select2 is licensed under MIT. In addition to a prepopulated menu of options, Select2 can dynamically create new options from text input by the user in the search box. This feature is called "tagging". To enable tagging, set the tags option to true :. Note that when tagging is enabled the user can select from the pre-existing options or create a new option by picking the first choice, which is what the user has typed into the search box so far.
Tagging can also be used in multi-value select boxes. Try entering a value that isn't listed in the dropdown - you'll be able to add it as a new option! Select2 supports ability to add choices automatically as the user is typing into the search field. Try typing in the search field below and entering a space or a comma. The separators that should be used when tokenizing can be specified using the tokenSeparators options.
You may add extra properties to newly created tags by defining a createTag callback:. You may control when Select2 will allow the user to create a new tag, by adding some logic to createTag to return null if an invalid value is entered:.

Getting Started Dynamic option creation. Dynamic option creation In addition to a prepopulated menu of options, Select2 can dynamically create new options from text input by the user in the search box.
To enable tagging, set the tags option to true : orange white purple.Select2 is a jQuery based replacement for select boxes. It supports searching, remote data sets, and infinite scrolling of results. Select2 also supports multi-value select boxes. The select below is declared with the multiple attribute. Select2 automatically picks up on this:. The placeholder can be declared via a data-placeholder attribute attached to the selector via the placeholder configuration element as seen in the example code.
Optionally, a clear button visible once a selection is made is available to reset the select box back to the placeholder value.
Select2 supports a minimum input setting which is useful for large remote datasets where short search terms are not very useful:. Select2 uses a function to load result data.
Here is a trivial example that creates choices that consist of user's input repeated a number of times:. Select2 allows the developer to limit the number of items that can be selected in a multi-select control.
In the example below only 3 or less items can be selected. Select2 provides some shortcuts that make it easy to access local data stored in an array instead of having to write a query function mentioned in the example above. Example below inlines the data by specifying an array in the data element. Items in such an array must have id and text keys. If your data does not have a text key, an alternative key can be specified as a string:.
In this example we will search for repositories using Github's API:. If this example stops working, you have most likely reached the usage limit for the GitHub Search API of 5 requests per minute. Please wait a few minutes and try again. An alternative transport function can be specified in the ajax settings, or an entirely custom implementation can be built by providing a custom query function instead of using the ajax helper.
Select2 supports lazy-appending of results when the result list is scrolled to the end. In order to enable the remote service must support some sort of a paging mechanism and the query function given to Select2 must take advantage of it. The following example demonstrates how this can be set up. Search for some keyword and then scroll the result list to the end to see more results load:. Note that when tagging is enabled the user can select from pre-existing tags or create a new tag by picking the first choice which is what the user has typed into the search box so far.
Select2 supports ability to add choices automatically as the user is typing into the search field. This is especially convenient in the tagging usecase where the user can quickly enter a number of tags by separating them with a comma or a space. Try typing in the search field below and entering a space or a comma. Note that the separators are defined in the tokenSeparators option. Note that this example uses the built in tokenizer function, but a custom one can be provided in the options.
Select2 can react to external value changes and keep its selection in-sync. This feature allows Select2 to work seamlessly with front-end frameworks that use data binding between ui components and model values. This feature is only available when initSelection function is provided in the options. This function is needed to map the choice ids set on the element to objects used by Select2. This function is set by default when Select2 is attached to a select or when the tags helper function is used.
Select2 supports drag and drop sorting of selected choices. Select2 does not, itself, provide the necessary code to perform dragging and dropping, instead it provides hooks that other libraries can use to provide the behavior.
